PRIMARY BATTERY.

Specification otsLetters Patent. Patented Mar, 11 1913,

Application filed April 23, 1912. Serial No; 692,737.

T 0 all whom it may concern:

Be it known that I, CHARLES B. SCHOEN- Mann, citizen of the United States, and resident of Waterbury, in the county of. New

Haven and State of Connecticut, have invented certain new and useful Improvements in Primary Batteries, of which the following is a specification.

This invention refers to galvanic batteries of the oxid-and zinc couple type and in a measure relates to improvements on that form of battery shown and described in my rior Patents Nos. 664,007 and 664,008. This type of battery therefore includes a negative electrode formed of, loose oxid of copper scale contained in a perforated fiat form of receptacle and employed in conjunction with a pairof zinc plate electrodes, the two. being msulatively connected and supported by a suitable suspending rodfrom the cover of the battery 'jar.

I A further feature of my invention is to support the oxid in a flat form of inclosed and portable receptacle that is made of perforated sheet metal, and in which is contained a corrugated or otherwise irregular form of perforated sheet metal conductin plate whereby a greater internal area 0 metal surface is brought into contact with the metal oxid, to obtain an increased amount of conducting surface; to so construct and proportion the receptacle that it may be employed in a suitable hanger or frame between the zinc plates in substantially the same manner that the present commercial forms of compressed copper oxid plates are used and supported by a single suspending rod from the cover of a jar.

Having the above objects in mind the invention includes the novel features of construction and arrangement of parts hereinafter referred, shown upon the accompanying drawings forming a part of this specification, in which similar characters of reference denote like or corresponding parts throughout the several figures and of which,

Figure 1, shows a perspective sectional view of my improved form of negative battery electrode coupled with a zinc electrode and contained within a battery jar. 2, is a cross sectional view taken on line va of Fig. 1, of my improved form of negative electrode detached, and, Fig. 3. is an edge view of a modified form of the same negative electrode supported in a different frame and coupled with differentstyles of zinc plates.

Referring in detail to the characters of reference marked upon the drawings 5 represents a battery jar, 6 the cover, 7 and 8 holes therethrough for the connection and support of theelectrodes,

9 represents a suspending rod by means of which the assembled electrodes are hung from the batte cover and detachably. connected thereto field wire 11 is also connected to the outer as shown in Fig. 1. In Figs. 1 and2the sup porting rod is' shown connected directly to centrally and vertically t erethrough, and having a nut or head 14 upon its lowerend,

tive electrode in, a manner to suppdrt the same.

tive electrode as contained in this application constitutes the emential feature of the invention when used in the manner and form herein shown, and as will be noted includes a substantially fiat shaped perforated covered receptacle 15 filled with loose oxid of copper scale 16 that constitutes the negative material of the electrode and which is penetrable from all sides by the solution contained within the jar. I also provide means for increasing the amount of metal surface for engagement with-the oxid by theemployment of an internally arranged corrugated sheet metal member 17, the pockets of which are preferably arranged vertically as shown in Fig. 2 to permit the receptacle to be filled from the top end. This contact sheet may also be perforated and in practice would be preferably arranged in. contact. with some portiousof the side walls of the 9 as shown in Fig. 2. This contact sheet is inserted in the receptacle prior to its being filled with the copper scale and before it is closed together. The particular manner of rial. but in practice wouldprobably be made of a single piece with the connected edge portions suitably seamed as is common m sheet metal work of this class. An electrode made in this way may be assembled and used in connection with a bent form of zinc 18 as shown in Fig. 1 or he supported from y means of nuts 10 10. A.

basket and likewise'with the suspending rod,

end of this rod by means of a third nut'12 the negative electrode 13 b being extended that fits againstthe under side of the nega The special form andconstruction ofnegaforming the receptacle is somewhat immate- M 'sulating block in a way to rigidly support a short hanger rod 9 as shown in Fig. 3, and used in connection with a metal frame 19 a porcelain block 20: and a pair of zinc plates 18-18 in substantially the same manner that I use a compressed plate.

In Fig. 1 the insulating washer 20 is threaded upon the rod 9 and supported upon the negative electrode 13 in a way to support the before mentioned positix 'e elec trode 18 which is further retained in position by means of a nut 21 and whereby the one electrode is suitably spaced and rigidly supported withrclationto the other. In Fig. 3, the negative electrode is provided with a metal frame member lfPthat encircles the edge portion of the receptacle and to which an insulating block 20 is connected. The posi tive plates 18* are in turn bolted to this inthe same. The second .ticld wire 22 is connected to the positive plates and is extended out through the hole 7 of the cover of the jar.

Having thus described my invention what I claim and desire to secure by Letters Patent is 1 In a primary battery of the class described, the combination of a flat form of negative electrode comprising a perforated sheet metal container, a single suspendingi rod extending through the container for supporting the same, a filling of loose oXid of copper within the container, a corrugated perforated metal sheet arranged in the oxid of the container, zinc electrodes insulatively supported upon the container and extending down opposite the two side portions of the negative electrode.

In a primary battery of the class described, the combination of a flat form of negative electrode comprising a perforated sheet metal container, a single suspending rod extending through the container for supporting the same, a filling of loose oxid of copper within the container, at corrugated perforated metal sheet in engagement with the walls of the container and suspending 1 0d arranged in the oXid of the container, zinc electrodes insulatimly supported upon the container and ex ending down opposite the two side portion. of the negative electrode.
